DETAILED DESCRIPTION

Description of specific structures and functions disclosed in embodiments of the present disclosure are only an example for describing the embodiments according to the concept of the present disclosure and the embodiments according to the concept of the present disclosure may be implemented in various ways. The present disclosure is not limited to the embodiments described herein and should be construed as including all changes, equivalents, and replacements that are included in the spirit and the range of the present disclosure.

It will be understood that, although the terms first and/or second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For instance, a first element discussed below could be termed a second element without departing from the teachings of the present disclosure. Similarly, the second element could also be termed the first element.

It is to be understood that when one element is referred to as being “connected to” or “coupled to” another element, it may be connected directly to or coupled directly to another element or be connected to or coupled to another element, having the other element intervening therebetween. On the other hand, it is to be understood that when one element is referred to as being “connected directly to” or “coupled directly to” another element, it may be connected to or coupled to another element without the other element intervening therebetween. Further, the terms used herein to describe a relationship between elements, that is, “between”, “directly between”, “adjacent” or “directly adjacent” should be interpreted in the same manner as those described above.

Like reference numerals indicate the same components throughout the specification. The terms used herein are provided to describe embodiments without limiting the present disclosure. In the specification, a singular form includes a plural form unless specifically stated in the sentences. The terms “comprise” and/or “comprising” used herein do not exclude that another component, step, operation, and/or element exists or is added in the stated component, step, operation, and/or element.

According to the present disclosure, a spacing member can be made of paper in an eco-friendly type which is the same material as boxes, so the spacing member can be recycled and can be fabricated at a low cost. However, the material is not limited to paper boxes and may be other materials that can be used for boxes.

According to the present disclosure, the spacing member has a simple structure and enables an article to be safely packaged in a body, whereby it is not damaged in carrying and can prevent damage.

A packaging system including the spacing member according to the present disclosure enables an article packaged in a boxy to be very easily taken out from the box, thereby being able to improve convenience for a user.

The spacing member according to the present disclosure has an advantage that it is easily and simply manufactured.

A spacing member 1 for a box according to the present disclosure includes a base 10 and a plurality of wings 20, 30, 40, and 50.

As shown in FIG. 1, the base 10 has a plurality of edges. According to an embodiment of the present disclosure, the base 10 may have four edges. In the four edges, pairs of edges facing each other are each symmetrically formed. In order to describe the present disclosure, the upper and lower edges are indicated by X₁ and X₃, respectively, and the left and right edges are indicated by X₂ and X₄, respectively. X₁, X₂, X₃, and X₄ may mean the lengths of the edges, respectively. Although only the base 10 is separately shown in FIG. 1 in order to make the drawings clear, it would be apparent to those skilled in the art that the base 10 is not necessarily formed separately from other parts.

Referring to FIG. 2, the wings 20, 30, 40, and 50 extend from the base 10. Since boxes generally have a hexahedral shape, four wings may be formed. However, the present disclosure is not limited thereto and the number of the wings may be increased or decreased. According to an embodiment of the present disclosure, the wings 20, 30, 40, and 50 may include an upper wing 20 extending from the upper side of the base 10, a left wing 30 extending from the left side of the base 10, a lower wing 40 extending from the lower side of the base 10, and a right wing 50 extending from the right side of the base 10.

The upper wing 20, left wing 30, lower wing 40, and right wing 50 each has a first section and second section. The first section is adjacent to the base 10 and extends from the base 10 and the second section extends outward from the first section. According to an embodiment of the present disclosure, when the surface on which the spacing member 1 for a box is placed is a rectangle, the upper wing 20 and the lower wing 40 are symmetrically formed, and the left wing 30 and the right wing 50 are symmetrically formed. The above case includes the case that the surface on which the spacing member 1 for a box is placed is a square, and in this case, the upper wing 20, left wing 30, lower wing 40, and right wing 50 are symmetrically formed.

A main folding portion is formed between the base 10 and each of the wings 20, 30, 40, and 50.

In the following description, the main folding portions may be indicated by ‘60’ or may be indicated by X₁, X₂, X₃, and X₄, respectively.

Sub-folding portions are also described in this way. The sub-folding portions may be indicated by ‘70’ or may be indicated by Z₁, Z₂, Z₃, and Z₄, respectively.

The main folding portions may be referred to as the upper edge X₁, the left edge X₂, the lower edge X₃, and the right edge X₄ or the base 10. The main folding portions X₁, X₂, X₃, and X₄ are formed such that the wings face to a side with respect to the base 10. Assuming in FIG. 2 that the direction coming out of the page surface is a front side and the direction going into the page surface is a rear side, the main folding portions X₁, X₂, X₃, and X₄ are formed such that the wings 20, 30, 40, and 50 face the front side. The folding portions X₁, X₂, X₃, and X₄ may be creases and are formed to enable the wings 20, 30, 40, and 50 to pivot with respect to the creases. In detail, when there is no external force applied to the wings 20, 30, 40, and 50, the wings 20, 30, 40, and 50 face the front side with respect to the main folding portions X₁, X₂, X₃, and X₄, and when an external force is applied to the wings 20, 30, 40, and 50, the wings 20, 30, 40, and 50 can be turned a predetermined angle with respect to the main folding portions X₁, X₂, X₃, and X₄.

The wings 20, 30, 40, and 50 have the sub-folding portions Z₁, Z₂, Z₃, and Z₄. The sub-folding portions Z₁, Z₂, Z₃, and Z₄ are formed at positions spaced a predetermined distance apart from the main folding portions X₁, X₂, X₃, and X₄. The sub-folding portions Z₁, Z₂, Z₃, and Z₄ are formed such that the wings 20, 30, 40, and 50 are partially formed in the opposite direction to the direction in which the wings 20, 30, 40, and 50 are folded by the main folding portions X₁, X₂, X₃, and X₄. That is, sub-folding portions Z₁, Z₂, Z₃, and Z₄ are formed such that the wings can be folded to the rear side with respect to the base 10. In order to describe the present disclosure, the sub-folding portion formed at the upper wing 20 is referred to as an upper wing sub-folding portion Z₁, the sub-folding portion formed at the left wing 30 is referred to as a left wing sub-folding portion Z₂, the sub-folding portion formed at the lower wing 40 is referred to as a lower wing sub-folding portion Z₃, and the sub-folding portion formed at the right wing 50 is referred to as a right wing sub-folding portion Z₄.

The first sections of the wings 20, 30, 40, and 50 are the parts extending between the main folding portions X₁, X₂, X₃, and X₄ and the sub-folding portions Z₁, Z₂, Z₃, and Z₄, respectively, and the second sections are the parts extending from the sub-folding portions Z₁, Z₂, Z₃, and Z₄, respectively. In order to describe the present disclosure, the first section of the upper wing 20 is referred to as an upper wing-first section 22, the first section of the left wing 30 is referred to as a left wing-first section 32, the first section of the lower wing 40 is referred to as a lower wing-first section 42, and the first section of the right wing 50 is referred to as a right wing-first section 52. Further, the second section of the upper wing 20 is referred to as an upper wing-second section 24, the second section of the left wing 30 is referred to as a left wing-second section 34, the second section of the lower wing 40 is referred to as a lower wing-second section 44, and the second section of the right wing 50 is referred to as a right wing-second section 54.

The base 10 has a plurality of edges. The base 10 has four edges, and accordingly, it is a rectangle in the drawings, but the base 10 is not limited thereto and may be changed into a circle, an ellipse, a polygon, etc., if necessary.

A main-folding portion 60 is formed between the base 10 and each of the wings 20, 30, 40, and 50. The main folding portions 60 are formed such that the wings face a side with respect to the base 10. Assuming in FIG. 1 that the direction coming out of the page surface is a front side and the direction going into the page surface is a rear side, the main folding portions 60 are formed such that the wings 20, 30, 40, and 50 face the front side. The folding portions 60 may be creases and are formed to enable the wings 20, 30, 40, and 50 to pivot with respect to the creases. In detail, when there is no external force applied to the wings 20, 30, 40, and 50, the wings 20, 30, 40, and 50 face the front side with respect to the main folding portions 60, and when an external force is applied to the wings 20, 30, 40, and 50, the wings 20, 30, 40, and 50 can be turned a predetermined angle with respect to the main folding portions 60.

The wings 20, 30, 40, and 50 extend from the base 10 with the main folding portions therebetween. Since boxes generally have a hexahedral shape, four wings may be formed. However, the present disclosure is not limited thereto and the number of the wings may be increased or decreased.

According to an embodiment of the present disclosure, the wings 20, 30, 40, and 50 may include an upper wing 20 extending from the upper side of the base 10, a lower wing 40 extending from the lower side of the base 10, a left wing 30 extending from the left side of the base 10, and a right wing 50 extending from the right side of the base 10. Although the four wings are referred to as upper, lower, left, and right wings herein for the convenience of description, this naming is not for limiting all the wings in the same configuration or different configurations. That is, all the wings may be the same configurations, or the detailed configurations or positions may be different.

The sub-folding portions 70 are formed at the wings 20, 30, 40, and 50. The sub-folding portions 70 are formed at positions spaced a predetermined distance apart from the main folding portions 60. The sub-folding portions 70 are formed such that the wings 20, 30, 40, and 50 are partially formed in the opposite direction to the direction in which the wings 20, 30, 40, and 50 are folded by the main folding portions 60. That is, sub-folding portions 70 are formed such that the wings can be folded to the rear side with respect to the base 10.

The wings 20, 30, 40, and 50 each have a first section and a second section. The first sections are the parts extending between the main folding portions 70 and the sub-folding portions 60, respectively, and the second sections are the parts extending from the sub-folding portions 70, respectively. In an exemplary embodiment of the present disclosure, the lengths of the second sections may be larger than the lengths of the first sections.

Similar to the main folding portions 60, the sub-folding portions 70 may be creases and are formed to enable the wings 22, 24, 26, and 28 to pivot with respect to the creases, in detail, the second sections of the wings 20, 30, 40, and 50 to pivot with respect to the first sections. In detail, when there is no external force applied to the wings 20, 30, 40, and 50, the second sections of the wings are bent to the rear side with respect to the first sections, and when an external force is applied, the second sections can be turned a predetermined angle with respect to the sub-folding portions 70. That is, the main folding portions 60 and the sub-folding portions 70 guide the wings 20, 30, 40, and 50 such that the wings can be bent in a predetermined direction.

According to an embodiment of the present disclosure, any one of the wings 20, 30, 40, and 50 may have a fixing portion 80 extending from the wing. As will be described below, the fixing portion 80 may be formed at the upper wing 20.

According to an embodiment of the present disclosure, the widths of the wings 20, 30, 40, and 50 are larger than the width of the base 10. For example, the second sections 34 and 54 of the left wing 30 and the right wing 50 may expand outward further than the first sections 32 and 52.

According to an embodiment of the present disclosure, the first sections 22 and 42 of the upper wing 20 and the lower wing 40 may expand outward from the main folding portions 60, and the first sections 126 and 128 of the left wing 30 and the right wing 50 may extend from the base 10 without expanding. Alternatively, according to another embodiment of the present disclosure, the first sections 22 and 42 of the upper wing 20 and the lower wing 40 may extend from the main folding portions 60 with the width maintained, and the first sections 126 and 128 of the left wing 30 and the right wing 50 may extend outward. When a pair of wings of two pairs of wings facing each other expands, an article put in a box can be more densely fixed when the spacing member 1 is put in the box.

According to an embodiment of the present disclosure, additional parts may be formed between the second sections 23, 34, 44, and 54 and the fixing portion 80. That is, an extension may be formed unless it critically interferes with the spacing box 1 that is brought in close contact with the inside of a box. The spacing member 1 according to the present disclosure has only to have the first sections and the second sections, but a possibility that additional parts such as third, fourth, etc. sections are connected unless they considerably interfere with the functions of the first sections and second sections of the wings is not excluded, depending on cases. However, only the first sections and second sections were described for the convenience of description herein.

Exemplary operation of the spacing member for a box according to the present disclosure is shown in FIGS. 6 to 8. According to an embodiment of the present disclosure, a packaging system including the spacing member for a box is provided, as described above. The packaging system according to the present disclosure includes a pair of spacing members 1 and a box. According to an embodiment of the present disclosure, the spacing members 1 may be integrally formed with a box or may be formed separately from a box and then inserted in the box.

According to an embodiment of the present disclosure, additional parts may be formed between the second sections 23, 34, 44, and 54 and the fixing portion 80. That is, an extension may be formed unless it critically interferes with the spacing box 1 that is brought in close contact with the inside of a box. The spacing member 1 according to the present disclosure has only to have the first sections and the second sections, but a possibility that additional parts such as third, fourth, etc. sections are connected unless they considerably interfere with the functions of the first sections and second sections of the wings is not excluded, depending on cases. However, only the first sections and second sections were described for the convenience of description herein.

A packaging system including a spacing member for a box according to the present disclosure includes two spacing members 1 and a box. According to an embodiment of the present disclosure, the spacing members 1 may be integrally formed with a box or may be formed separately from a box and then inserted in the box.

The spacing members 1 are disposed on two sides facing each other of the inner sides of a box. The spacing members 1 are disposed such that the ends of the wings 20, 30, 40, and 50 are in contact with the edges of the inner sides of the box, respectively. Since the second sections 24, 34, 44, and 54 of the wings 20, 30, 40, and 50 are longer than the first sections 22, 32, 42, and 52, respectively, a space is formed between the base 10 and an inner side of the box and gaps from the sides being in contact with the wings 20, 30, 40, and 50, respectively, are formed by the main folding portions 60 and the sub-folding portions 70. Accordingly, the box can be manufactured at a low cost and can be safely carried with shock prevented by the spacing members 1 that can be made of the same material as the box.

Coupling portions 111 that can be coupled to the fixing portions 80 of the spacing members 1 are formed at the box. According to an embodiment of the present disclosure, the fixing portion 80 may extend from the upper wing 20 the wings. The fixing portion 80 may be smaller than the widths of the wings 20, 30, 40, and 50. Accordingly, the coupling portion 111 may be formed such that the fixing portion 80 can be fitted in the box. According to an embodiment of the present disclosure, the coupling portion 111 may be a passing surface through which a surface of the box partially passes.

The spacing members 1 are disposed on two sides facing each other of four inner sides of a box. The spacing members 1 are disposed such that the longitudinal free ends Y₁, Y₂, Y₃, and Y₄ of the second sections of the wings 20, 30, 40, and 50 are in contact with the edges of the inner sides of the box, respectively. Since the spacing member 1 according to the present disclosure satisfies [Formula 1] to [Formula 4], a space is formed between the base 10 and n inner side of the box, and gaps from the sides being in contact with the wings 20, 30, 40, and 50, respectively, are formed by the main folding portions X₁, X₂, X₃, and X₄ and the sub-folding portions Z₁, Z₂, Z₃, and Z₄. Accordingly, the article placed between the spacing members 1 can be stably supported and protected, and damage to the article due to shock that may be applied when the box is carried can be prevented.

That is, an article to be packaged is placed between the bases 10 of the spacing members 1 disposed on the inner sides of the box. The article to be packaged may be another box that has rectangular surfaces the same as the shape of the base 10 and is put in the box. The article to be packaged is fixed by the bases 10 of the spacing members 1 disposed at both sides in the box and is spaced apart from the inner sides of the box by the wings 20, 30, 40, and 50.

According to the present disclosure, a packaged box can be very easily taken out of the box. The upper wing 20 is flat when packaging, as shown in FIG. 6. When two sides of the upper wing 20 are pulled up, that is, the upper wing 20 is turned substantially 90 degrees with respect to the main folding portions X₁, X₂, X₃, and X₄, as can be seen in FIG. 7, both spacing members 1 are moved along the inner sides of the box 1 and protrudes outside, so the article packaged between the spacing members 1 can be easily taken out. Accordingly, convenience for a user can be increased.
